Suppose you have two small plants. You cut the roots off of one and then place both plants in a jar of red dye. After 20 minutes, the roots, stem, and leaves of the plant with roots have turned pink. The plant without roots has not changed color at all. Why has the plant without roots remained a normal, green color?

The plants absorb water through the phenomenon of osmosis where water moved from area of high concentration to area of low concentration through a semi permeable membrane.

When the plant with roots was placed in a jar of red dye, the roots absorbed color water due to which the color of stem and leaves turned pink.

On the other hand, when plant with no roots was placed in the jar, the mechanism of absorbing water was removed since the roots were removed. That is why, the plant without roots could not absorb the colored water and remained green with no color change.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.

i'm guessing this is from edg enuity so the answers would be, from top to bottom,
